Some jurisdictions do require a civil engineer for individual lot grading plans, though I am not at familiar with the process in Florida.

My Mom invested in RE so I sort of had the AHA moment as a teenager but got good grades, went to college, worked at, in hind-site, stupid but maybe character building low paying jobs while attending school, graduated, joined the rat race with a job I loved for a long time, met my wife, had a child. 

I have one in a below grade toilet and that is where I have mostly had them used.

What tightens up the market even further is that more rental grade SFR's than ever are being held by private investors and they are not thinking about selling. 

There plenty of other opportunities elsewhere, my clients are involved in institutional grade properties across the country.

There was a small amount of water in the front of the house basement area which I attributed to negative grading in that area. 

I have put architectural grade shingles on houses where everyone else had plain old 3 tabs and since my houses always showed better than others in the neighborhood, paint etc, I feel I got my money's worth.

Yes of course your ROI won't look as sexy on paper but it's a give & take, which you get or you'd be looking for $30k properties.For Cleveland specific research I'd check out The Ultimate Guide to Grading Cleveland Neighborhoods.

Just so we are all on the same page Parma would be a B-Grade Neighborhood but Old Brooklyn is by no means a B-Grade Neighborhood.

My significant others' parents will likely only approve of a higher grade property.
